To all whom it may concern:

Be it knownthat l, WILLIAM TORPEY, a citizen of the United States, and aresident of the cityof Chicago, county ofCook, and

State of illinois, have invented certain new has for its object the production ofa device i of this character through "the medium fof which the interior` of a tubular boiler may be readily and expeditiously cleaned. e 1 e `A further object isthe production of a device.` of this character which will be of durable and economical construction, one

into and removed from a boiler, and further; one which will behighlyetlicicnt in use.

Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and claimed. e e e The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a longitudinal section through a conventional form of a tubular boiler in which is arranged'a cleaning device, embodying the invention, e n i Fig. 2 is a section taken on line m-wof Fig.` e e Fig. 3 isa central vertical section ofa portion of the device, and j e e Fig. 4 is a sectional. view of another form of the invention. l

` One form of construction as illustrated in the drawings comprisesa shoe or support lfwhich consists primarilyoftwo spaced parallel members adapted, when the device `is in use, to engage with and ride `uponthe bottom of the boiler A in conjunction with which the device is employed. Said side members of the shoe 1 are rigidly connected by means of integral `cross bars 2 and 3, a pipe 4 arranged in said shoebeing anchored at one end in the cross piece 2. Sald pipe 4 is adapted for connection with a `fluid supply pipe 5, a suitable connecting member Gebeing employed to effect such connection.

f `The pipe 5 is of a sectional naturein order :Specicaton `of Letters Patent.

in order to adapt the device` for use in lcon-l e nection with boilersof any size or length.

Arising from `the shoe `lis `an `elongated tubular spraying element 7 "adapted,"when in use, `to engage between the tnbesfBfof `the .boiler in connectionfwith which "the device `is employed.` rlhe spraying element I7 is formed with spaced laterally discharge" openings 7 and a terminal perforated discharge nozzle'i."

cof,

Thelower `end of spraying eleinentli` ing trunnions `9 which `pivotally engage in the opposite sides of `shoe 1. `The arrangement is such thata connection between" the rigidly secured in a collar orholder 8l havspraying device and the shoeis effected which "permits ofpivotal movement of said which may be readily and easily inserted element in a vertical longitudinal plane. `To hold the `spraying element in vertical or operativepositioma cross barllO is provided which connects thenpper ends ofthe "side ing element is adapted to engage, a strap 11 pivotally connected at 12 `Withone` side of shoe 1 being adapted to coperate "with the bar 10 in embracing the lower end of the .y l

vertical position. A thumb nut13`is adaptL ed for releasableengagement with thefree end of strap" 11 in "locliingthelatter in operative position.

. When the spraying element iisin vertical or "operative position, the lower "end thereof is adapted for connectionwith` the u wardly turned forward `endof pipe "4J nTiiis connection is effected by means of athreaded union 14 adaptednfor `engageinent with the l reduced threadedlower end of collar 8, the

lower" end `of said union` `provided with an lnwardlyiproJecting annular flange `spraying element to hold thesaine rigid inj le e `which is adaptedfor engagement withan outwardly projectingtlange provided upon "8, the forward end` of pipe 4`will spring downwardly in order. to allow for `clearance` ofthe lower end.of"member""7 whenjthe latter is `rocked to horizontal orinoperative position,` as seen'in dotted "lines in To-permit of ready/access be1ng1,`ga1ned to theunion 14, the opposite sidesnf"slide1` are provided with openings 15 as clearly seen in Figs. 1 and 2.

To further securely brace the spraying element when in vertical or operative position, a brace rod 16 is provided, rp'ivotally connected at its upper end as at 17 with said spraying element, the lower end of said brace rod being releasably connected with the cross bar 2 of the shoe 1 by means of a removable pin 18. When it is desired to swing thespraying element downwardly to inoperative position, the pin 18 is removed inl order to releasethe rod 16.

j Inl using the device the same is inserted through the opening C usually provided at oneeiid of a conventional boiler. 1n this insertion the spraying element 7 is of course in lowered position, as shown in dottedlines in Fig. 3. After insertion of the device, the spraying element 7 .is swung to vertical yposition and` lockedby means of strap 11 and brace rod 16. `This having been done the connection of the lower end of the spraying device with the pipe 4 is readily and easily effected through manipulation of the union 14. Cleansing Huid is then supplied through the pipe 5', the fluid thus applied being sprayed from the element 7 through the openings 7 and nozzle 7, which resultsyin a thorough cleansing of the interior of the .boiler and the exterior surfaces of the tubes B. l The supply pipej is used to move the device longitudinally of the boiler iii the cleansing operation. In the removal of the device from the boiler` after the cleasing operation, the spraying element is of course released and rocked to its lower or horizontal position. u s

Ifdesired the entire construction may be greatly simplified by forming thel lower end of the spraying element 7 integral with a shoe or4 support 1, in which is formed -a passage 4 adapted for 'connection with the pipe 5, a union 6 beingv employed the connection. T he shoe 1` is veryshort so as to permitof insertion ofthesame throughftlie opening `C of the boiler. 1n other words the length of said shoe` will be less than the dia- Ameter of. said opening. In either form the ends of the shoe are rounded so as to permit Vof the same readily riding over all obstructions such as rivet heads, overlapping ends of sheet metal wall sections and the like, when the device is moved longitudinallyin the boiler. y

Vhile I have illustrated and described the preferred forms-.of construction for carrying my invention into effect, these are capable of variations and modifications without de- Yparting'from the spirit of the invention. I,

. therefore, do not wish to be limited to the precise details of construction set forth, but desireto avail myself of such variations and modifications as come within the scope of the appended claims.
